Figure 9
PMMA cylinder of 1 mm diameter (a) imaged at 30 keV, CB = 0, 2 mm PSW with R2 = 4.03 m. (b) Phase-retrieved image (Paganin et al., 2002BB41) with d = 2.96 × 10−7 and b = 1.16 × 10−10, where the grey scale is proportional to the thickness of the object. Analysis of the phase-retrieved image shows an accurate measurement of the known diameter of the cylinder, as can be seen in (c) the average line profile of (b), showing the width and depth of the cylinder to within 10% of the known value.
